Abstract
The invention discloses a glass powder lubricant used for hot-rolling of seamless steel pipes, wherein the glass powder lubricant is characterized by being prepared by the following raw materials: 20-40 parts of glass powder by weight, 5-20 parts of boron nitride by weight, 10-30 parts of sodium borate by weight, and 5-10 parts of fatty glyceride by weight. After being mixed with boron nitride melt and sodium borate melt, the glass powder in the glass powder lubricant can automatically generate a lubricating film which is featured with high property in resisting extreme pressure. The film is liquid mixed glue and has good lubricating property in the pipe hot-milling process at 1000-1200 DEG C after being mixed with an active agent whether the relative sliding velocity of friction couple pairs is large or small, so as to exert the effect of heat dissipation and heat insulation. And meanwhile, oxidization and decarburization are avoided, so that the novel glass powder lubricant is formed by mixing the above components at certain proportions.
Description
Technical field
The present invention relates to the covering property novel lubricant for hot rolled seamless steel tube, particularly for the glass powder lubricant of hot rolled seamless steel tube.
Background technology
Carrying out titanium alloy, superalloy causes inner wall oxide, decarburization easily and oozes hydrogen when stainless steel and other metal materials is rolling.Need a kind of lubricant can play anti-oxidation, as to prevent decarburization, antiseepage hydrogen effect, also need the phenotype drag of good lubricated, adiabatic and reduction forging simultaneously, in the work-ing life of improving mould, forging can obtain higher surface quality.
Chinese patent publication number CN101376142 discloses a kind of glass powder that uses as the production technique of titanium or titanium alloy section bar special lubricant for squeezing, also glass lubricant evenly can be attached on the masterbatch by the form of passing with solid-state form after the masterbatch heating.Glass lubricant plays lubricated, and is anti-oxidation, the effect of protective money metal surface.It also can be applicable to other metallic substance that adds hot-work by extrusion machine.Can also be applied to simultaneously the protection against oxidation layer in the metallic substance forging process.The present invention adds the metallic substance of hot-work with titanium or titanium alloy and other by extrusion machine, and through extrusion machine, extrusion molding has reduced cost significantly, and economic benefit obviously improves; Adopt inexpensive glass powder as lubricant rather than use metallic lubricant, can not cause masterbatch to pollute, improved the section bar surface quality.
Chinese patent publication number CN101735879 discloses a kind of titanium alloy extrusion lubricant and preparation and using method, and lubricant is made up of following compositions by weight percentage: W glass: 60～65%, heat resistant type water soluble cellulose: 20～25%, water: 10～20%.Prepare W glass in proportion, shrend, oven dry obtains the W glass powder through grinding, and with W glass powder, heat resistant type water soluble cellulose, water mixing and ball milling, obtains titanium alloy extrusion lubricant again.This titanium alloy extrusion lubricant use temperature can not be above 1000 ℃.
Chinese patent publication number CN1618566 discloses a kind of squeezing-forging and has met forming technology, and its protecting lubricant that adopts is made up of GL08 glass powder, GL09 glass powder and FRS1 resin glue.This protecting lubricant can only use down at 800 ℃～960 ℃.
Summary of the invention
Technical problem to be solved by this invention is can not be higher than 1000 ℃ problem and a kind of glass powder lubricant is provided at existing lubricant use temperature, the use temperature of this glass powder lubricant is higher than 1000 ℃, in the tube rolling process, can play the resistance to deformation of anti-oxidation, anti-decarburization, antiseepage hydrogen, thermal insulation and reduction forging, and raising die life, play heat radiation and heat insulation effect simultaneously, significantly reduce hot extrusion pipe surface pressing pit, defectives such as ditch bar, roughness value reduces significantly.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
The glass powder lubricant, its feedstock production by following weight part forms: 20～40 parts in glass powder, 5～20 parts of boron nitride, 10～30 parts of boraxs, 5～10 parts of glycerin fatty acid esters.
In a preferred embodiment of the invention, described glass powder lubricant is formed by the feedstock production of following weight part: 40 parts in glass powder, 30 parts of boron nitride, 20 parts of boraxs, 10 parts of glycerin fatty acid esters.
Preparation method of the present invention is: above-mentioned each component materials is mixed, get mixing powder and obtain the regulation granularity by fully effective stirring and processing, packing is preserved, warehouse-in.
The autonomous strong lubricant film of anti-extreme pressure ability that generates of glass powder in the glass powder lubricant of the present invention and boron nitride melting attitude and borax melting attitude mixing energy.This film is the liquid jelly that mixes, with promoting agent be blended in 1000～1200 ℃ of following tube rollings the time friction couple relative sliding velocity when no matter large or small, good lubricity is arranged, can play heat radiation and heat insulation effect.Simultaneously, can be anti-oxidation, anti-decarburization, thus above component mix by a certain percentage, be a kind of novel glass powder lubricant.
